Shearing is a metalworking process that involves cutting or trimming metal sheets or plates using shear forces. This process is commonly used in industries such as automotive, aerospace, and construction.
The principal parts of a drilling machine include:
1. Base: The base is the foundation of the drilling machine and provides support and stability during operation.
2. Column: The column is a vertical structure that supports the arm and spindle assembly. It also houses the motor and drive mechanism.
3. Arm: The arm is a horizontal structure that is attached to the column and can be moved up and down to adjust the height of the drill bit.
4. Spindle: The spindle is the rotating shaft that holds the drill bit and is responsible for drilling holes in the workpiece.
5. Drill head: The drill head is the assembly that contains the motor, gears, and other components that drive the spindle and drill bit.
6. Table: The table is a flat surface that supports the workpiece during drilling operations. It can be adjusted in height and angle to accommodate different workpieces.
7. Drill chuck: The drill chuck is a device that holds the drill bit in place and allows for easy changing of drill bits.
8. Feed mechanism: The feed mechanism is responsible for moving the drill bit into the workpiece at the desired speed and depth. It can be manual or automatic, depending on the type of drilling machine.

Shearing
Shearing is a metalworking process in which a thin sheet of metal is cut by applying a shearing force that causes the material to fracture along a straight line. The shearing force is applied using a sharp-edged tool called a shear blade.
Principal Parts of a Drilling Machine
- Base: The base is the foundation of the machine and provides stability during operation.
- Column: The column supports the spindle and drilling head. It provides vertical movement for the spindle.
- Head: The head holds the spindle and feeds the drill bit into the workpiece. It can be moved vertically along the column.
- Spindle: The spindle is a rotating shaft that drives the drill bit.
- Chuck: The chuck holds the drill bit in place. It can be tightened or loosened to secure the drill bit.
- Drill bit: The drill bit is the cutting tool that creates the hole in the workpiece.
- Table: The table supports the workpiece during drilling. It can be moved horizontally and vertically to position the workpiece under the drill bit.
- Feed mechanism: The feed mechanism controls the rate at which the drill bit moves into the workpiece.
- Speed control: The speed control regulates the rotational speed of the spindle.
- Depth stop: The depth stop limits the maximum depth of the hole that is being drilled.
